Can't get any data in FF22

[gdipkf1986]

the kick not working, no any audio data
soundmanager v297 also got same problem, but it's works well if set preferFlash: true

----------------------------- update -------------------------------------
Found the reason, I commented some lines because the insecure operation, so the it can't get audio data. It backs work once uncomment the lines, but insecure operation appear again when playing local file.
